AIR COOLING SYSTEM FOR HEAT TRANSFER AGENT Russian patent published in 2006 - IPC F28D1/04 

FIELD: power engineering, namely systems for air cooling of heat transfer agent pumped through heat exchange equipment, possibly heat removal from second circuit of nuclear plant.

SUBSTANCE: high power system for air cooling of heat transfer agent is in the form of recuperative heat exchanger and it is made of vertical bundles of finned tubes housed in polyhedral casing and assembled to sectors from which full heat exchanging surface is formed. Said full heat exchanging surface is in the form of cone with apex turned downwards. Above cone there is pressure annular manifold with radial dispensing branch pipes; under cone there are accumulating annular manifold with discharging radial branch pipes. In lower part pipelines with sprinkling water jets turned upwards are arranged. Between annular manifolds dampers are mounted for controlling air supply into heat exchangers. Invention enhances appearance of industrial object due to prevention of steam generation over it and lowering intensity and repetition frequency of acidic rains and mists.

EFFECT: enhanced appearance of industrial object, reduced contamination degree of sanitary-technological zone.
